Rated 5 out of 5 by Best Bang For Your Buck Amazing machine. I have been looking for a gas pressure washer for quite some time now. The fit and finish is second to non. Pressure is amazing and I like that you can select different pressures for different situations. The rubber handle feels great and the trigger isn't hard to hold down unlike other models I have owned. I found the hose and gun storage worked perfect. I wish I could include a picture to show how I store everything. Definitely recommend this machine. You will not be disappointed. July 12, 2016
Rated 5 out of 5 by Great machine The engine starts easily and is quiet. The washer performs very well. The only thing I don't like is the hose storage and would really wish the hose was not as stiff. May 6, 2016
Rated 3 out of 5 by Evaluate Construction Overall good specs on paper. However look at how it is built. Here are the downsides: 1. Handle is made out of plastic. Don't try to lift this unit using the handle or you will likely break it. 2. Handle has fold down pivot joints. In theory this sounds great! But in practice this is the weakest part of the handle assembly, they should not have put in this useless feature. It saves very little space, and reduces the integrity of the unit as you can no longer lift it up via handle without feature of breaking the plastic hinge joint. May 4, 2016
Rated 5 out of 5 by Works Great ! Works really well easy to set up you'll be happy you got it. Thanks Generac April 7, 2016
Rated 5 out of 5 by Great Price for a great product I couldn't be happier with my purchase of the Generac Power OneWash. I have been waiting for spring to arrive to be able to get it out and use is again for the season. I am a disabled veteran, and have difficulty walking and use a cane. This washer has been easy for both my wife and I to use. April 7, 2016
Rated 4 out of 5 by Nice and powerful Nicely built pressure washer with lots of power to get the job done. April 6, 2016
Rated 5 out of 5 by Second Generac power washer, will buy more if needed! My original Generac power washer was near ten years old and had heavy use over the years. When parts were needed in the pump to keep it going, because of its age, some of the small parts were obsolete! Went out and bought a new Generac, that was capable of higher pressure settings, and paid a bit less then I did for the one I bought ten years ago...! I did not want to trash my old washer because the engine ran so great, therefore I found a new pump that fit, ordered it, and now I have two great power washers, and am very happy with both.

Rated 5 out of 5 by Really a great machine for the cost Ran and tested it, and was amazed at how easy it is to use and operate. Super nice! December 14, 2015
